Los Angeles International to Dubois Municipal LAX → DUB

706 nautical miles (812 statute miles) northeast on a straight line, true course 033°, about 021° magnetic at the departure end (variation 12E). At 120 knots that is 3 h 51 min at the quickest height in today's winds (30,000 ft, a 63-knot tailwind), arriving about 12:00 pm MDT (18:00 UTC). Right now LAX is VFR, wind from the east (090°) at 6 knots; DUB is low IFR, wind from the south-southeast (160°) at 3 knots. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools. Airlines fly this pair: 654 flights in the DOT's last twelve reported months, the route's page.

A SIGMET warns of weather hazardous to all aircraft; an AIRMET of weather that matters to small aircraft and to flying without instruments. "From 60 to 180 nm out" is measured along the route from LAX.

Based on data from the 12th at 06:00 UTC; valid on the 12th at 12:00 UTC for use 08:00 to 15:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; a height is left out when the forecast has no wind for it over most of the line (the ground is higher). Ground speed is the airspeed less the headwind; the time en route is for the straight line and ignores climb, descent and routing around weather.
